- Page 24 MAINTENANCE AND OPERATION The water heater is automatic in its operation. It will maintain a full tank of water at the temperature setting of the controller. The water heater should not be turned on without first making sure that the tank is full of water and that all air has been released.
- Page 25 ANNUAL INSPECTION 1. Monitor water temperature a. Let water heater completely heat to a designated temperature setting. b. After controller satisfies (that is, when the magnetic contactor actually clicks off), draw water from as close as possible heater outlet and measure the temperature.
- Page 26 Flush the cleaned ends of the elements with clean water. i. Re-install element with new o-ring. j. Re-attach element wires. k. Continue until all heating elements are cleaned. l. Fill the heater following the filling instructions provided in Section II and check around the elements for leaks.
- Page 27 Check for mineral buildup on the probe and clean as required. Check for continuity between the yellow wire and ground. See diagram 2 on the following page. 4. Err, H2O, LEA a. This message displays if the leak detection sensor determines there is water in the base of the heater shell.
- Page 28 GENERAL TROUBLESHOOTING Symptom Water reaches setpoint Low incoming water temperature but does temperature. not last through the entire dishwasher Incoming water cycle. temperature is dropping. Water pressure is too high. Booster heater may be undersized. Incorrect voltage. If two magnetic contactors are utilized, one is not energizing.
- Page 29 Symptom Probable Cause Temperature and No pressure reducing pressure relief valve valve or wrong valve seeps installed causing excessive pressure in the unit. Pressure reducing valve bypass is blocked. Anti-siphon valve or check valve installed in the warm water inlet line.
- Page 30 CONTROL BOARD (T1000) / DISPLAY (TD1000) TROUBLESHOOTING 1. Verify proper power supply voltage between each phase (L1 to L2, L2 to L3, and L1 to L3). The power supply voltage should match the voltage listed on the booster nameplate. If voltage is incorrect, check main supply wiring or replace unit with proper booster heater.
- Page 31 on the T1000 control board. If no voltage is present, replace the control board (T1000). If voltage is present, check for voltage across the contactor coil. If voltage is present at the contactor coil, replace the magnetic contactor. If no voltage is present, verify that the booster heater is wired according to the proper wiring schematic for the unit.
- Page 32 SECTION V – Before servicing or replacing any part, make sure to turn the power supply to the unit OFF. HEATING ELEMENT 1. Disconnect power from unit. 2. Shut off incoming water supply. 3. Attach hose to drain connection. 4. Lift manual release lever on relief valve to let air into system or break union on outgoing water line.

Reconnect wires disconnected in step 2. NOTE: When reconnecting the ribbon cable, be sure to have the key on the cable align with the slot in the connector. 6.
- Page 34 Note: It is unnecessary to unscrew the thermowell from the vessel to replace the P65 sensor. 5. Insert the new P65 sensor assembly into the P65 thermowell. Be sure to insert the sensor until the shrink-wrap cap engages the threads on the end of the thermowell. Note: The new sensor and cord assembly is push-fit onto the end of the thermowell threads.
